SAMUEL HOBSON, OF NEW YORK, N. Y.

IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 156,925, dated November17, 1874; application filed August 15, 1874.

To all 'whom fit may concern:

Be it known that I, SAMUEL HoBsoN, of New York, in the county of NewYork and State of New York, have invented a new and Improved Gas-Burner,of which the following is a specification:

Figure l is a central longitudinal section of my improved gas-burner,and Fig. 2 is a top View of its upper diaphragm.

Similar letters of reference indicate corresponding parts in both thefigures.

This invention has for its object to so construct a gasburner that itwill neutralize an excessive degree of gas-pressure, and produce asteady flame and perfectcombustion, even under excessive pressure.

My invention consists in arranging within the shank of the burner two ormore diaphragms, which have eccentric perforations at opposite sides,and serve to detain and deect the gas during its passage to the flame.

In the drawing, the letter A represents a gas-burner of suitable sizeand shape. Within its shank or lower part is formed an enlargement orchamber a, within which there is placed a diaphragm, b, of sheet metalor other material. This diaphragm extends entirely across the chamber a,as shown. Thegas, ascending toward thel escape opening ofV the burner,will strike the solid center of the diaphragm, and will thereby bedetained and deilected toward one or more openings formed near the edgeof the diaphragm. Thus, by this diaphragm b, the gas will be detainedand an excessive supply to or pressure within the flame will beprevented 5 but one such eccentrically-perforated diaphragm will n-otsuffice in many cases, and I therefore use a second diaphragm, c, aboveb. This second diaphragm is also perforated, near the edge, and has itscenter bent down into contact with b, and its holes diametricallyopposite to the holes in b, as indicated in Fig. 2. The gas ascendingthrough the apertures in b will then be further detained by thediaphragm c, and will have to pass round the depressed center of c totheapertures on the opposite side before it can escape to the top of theburner. Thus, by the two diaphragms, the object of the invention, ofcausing an unnecessary loss of gas to consumers, will be fully attained.

It is evident that instead of depressing the center of the diaphragm cthe same result will be obtained by raising the center of b.

I do not claim, broadly, the arrangement of perforated diaphragmsconnected at their centers and pierced at opposite sides of theircenters, as that is shown in the Patent No. 109,404; but

I do claim- The gas-burner A, combined with .and containing in itschamber a the two diaphragms b and c, perforated at opposite sides oftheir contiguous centers, substantially as herein shown and described.
